- Answer: Left Axis Deviation (LAD) refers to the pattern of electrical activation that occurs in the heart. LAD is an EKG-specific finding and not necessarily indicative of any specific cardiovascular condition. In fact, LAD is the most common EKG abnormality observed in adults, occurring in almost 10% of the adult population.

Top 30 Doctor insights on: Left Axis Deviation Health Risks Get help from a doctor now ›. Axis: The preponderance of electrical activity of your heart is directed to the left of your body. This may mean your left ventricle is thickened (hypertrophy), or may be caused by a minor conduction delay (left anterior hemiblock).

- The mean absolute deviation is the average of the positive distances of each point from the mean. The larger the MAD, the greater variability there is in the data (the data is more spread out). The MAD helps determine whether the set's mean is a useful indicator of the values within the set.

ECG Axis Interpretation If the QRS is isoelectric in any given lead (positive deflection = negative deflection), the axis is at 90 degrees to this lead. The diagram below illustrates the relationship between QRS axis and the frontal leads of the ECG. Image reproduced from Chung. 1  Normal Axis = QRS axis between -30 and +90 degrees. 2  Left Axis Deviation = QRS axis less than -30 degrees.

- The right-hand rule helps amateur astronomers understand axial tilt. When the fingers of the right hand are curled in the direction of the planet's rotation, the thumb points in the direction of the planet's North Pole. An axis is an invisible line around which an object rotates, or spins. The object can be a tiny particle, smaller than a single atom. Or it could be a star with the mass of a thousand suns.

Axis Tilt and Axis Rotation Axis tilt is the vertical angle at which the ball rotates. Axis tilt is what is commonly known as spin. Axis tilt is determined by the position of the thumb during the release. If the hand turns too early, the thumb exits on top of the ball. Bowlers with a high degree of axis tilt will be able to see the top of their hand during the release and follow through.

Which Mental Health Conditions Were Classified as Axis I Disorders? Axis IV disorders refer to psychiatric problems caused by recent environmental and psychosocial stressors. This includes the death of a loved one or a major life change, such as getting laid off or having a spouse leave. These stressors can compromise diagnosis and treatment of a mental health condition.

Anxiety Causes Palpitations to Cause Anxiety It's well known that anxiety can cause heart palpitations, and it's believed that the main cause may be an over-awareness of one's own heart, combined with surges of adrenaline that may occur at random in those with anxiety. These types of palpitations often trigger panic attacks. Panic attacks themselves can also cause palpitations. During a panic attack, two things occur that lead to rapid heartbeat: First, the sympathetic nervous system is on high alert, which may lead to a rapid increase in heart rate. Second, during panic attacks, people often have a tendency to hyperventilate.

- The sum ofsquared deviations about the regression line is a measure of the ex-tent to which the regression fails to explain the dependent variable (ameasure of the noise). Hence, the R 2 statistic is a measure of the ex-tent to which the total variation of the dependent variable is ex-plained by the regression.

Astronomical Coordinates Declination (delta): angular distance from the celestial equator (+=north, -=south). Right Ascension (alpha): angular distance along circles parallel to the equator. Define zero point to be the vernal equinox, the point where the Sun's position crosses the celestial equator as it moves north. Right ascension increases going eastward. Dec is measured in degrees, minutes of arc, seconds of arc, or decimal degrees.
